WOVEN PILE FABRIC.

Specication of Letters Patent.

' Patented May 12, 1914.

Application filed September 24, 1913. Serial Nb. 791,513.

To all 'whom 'it may concern:

Be it known that I, Hnc'ron LE D oUx, a citizen of the United States,residingl at Worcester, in the county of WVorcesterand State ofMassachusetts, have invented cerwhich is woven double, by carrying thepile Vwarps back and forth between suitably spaced backing webs, andinterweaving the pile warps witheach of the'backing webs, said pilewarps being afterward cut midway between the backing webs, so that 'eachwill have a cut pile facing or surface thereon.

My invention more particularly relates tol woven pile fabric used forcocoa mats, etc., in which the warp, and pile are of heavy and coarsecharacter.v

The object of my invention is to improve upon woven pile fabrics of theclass referred` to, and to provide a woven pile fabric of the classreferred to, which can be woven on an automatic loom which ispreferablyprovided with needles for inserting the weft threads.

In myy improved woven pile fabric, the two backingwehs are preferably.of uniform structure, each having weft threads extending insubstantially the same horizontal plane, and two sets ofbinder warps,crossing each other at regular intervals upon the weft threads, to bindand hold said weft threads, vand each backing web also having a secondsetof weft` threads, extending upon the outerside of the binder warps,and in the same vertical plane as the first mentioned weft threads, andtwo sets of /pile'warps, passing back and forth between the two backingwebs, and passing around the weft threads on the outer side of thebacking webs, said pile warps crossing each other intermediate thebacking webs, prior to being cut to form a cut pile surface, and eachset of pile warps forming close loops on the backin webs, to make whatis termed a diamond back on the woven fabric.

My invention consists in certain novel features of construction of mywoven pile fabric as will be hereinafter fully described.

In the drawing is'shown a detached section of a woven double pile fabricembodying my improvements; the section is taken in the direction of thelength of the fabric, and at the right the pile warps are shown cut,intermediate the backing webs, to produce a cut pile surface on eachfabric.

In the accompanying drawing, 1, and 2 are two sets of binder warps inone backing web, which are crossed at' regular intervals, to bind andhold the weft or filling threads 3, which are inserted through the shed,preferably by means of a needle. .4, and 5 are two sets of binder warpsin the other backing web, which are crossed at regular intervals,

to bind andhold the weft threads 6, which are inserted through t-heshed, preferably by means of a needle.

7 and 8 are the two sets of pile war s which are carried back and forthbetween t e two sets of binder warps 1 and 2, and 3 and 4, andarecrossed, as shown at' the left in ythe drawing, intermediate said twosets of binder warps. With the two sets of binder warp threads 1 and 2is combined an outer set of weft threads 9 which extend in the samevertical plane, as theweft threads 3, and with the other set of binderwarp threads 4 and 5, is combined an outer set of weft threads 10, whichextend inJ the same vertical lane as the weft threads 6. The set of pilewarps 7 pass around the outer weft thread 9 on the upper backing web,and then around the outer weft thread 10 on the lower backing web, saidouter wefts 9 and 10 are not in the salne vertical plane, as shown atthe left in the drawing. he sets of pile warps 8 pass around the outerweft thread 10 on the lower backing, and then around the outer weftthread 9 on the upper backing, said outer weft threads 10 and 9 are notin the same vertical plane, so that the two sets of pile warps 7 and 8,form two Sets of close loops, arranged alternately on the back of thebacking webs, and forming what is termed a diamond back. After thefabric is woven', as shown at the left in the drawing,the sets of pilewarps 7 and 8 are cut or severed, intermediate the two backing webs inany ordinary way, forming two separate pile,fabrics, each having a cutpile facing or surface, as shown at the right in the drawing.

My improved double pile fabric may be 'woven on any suitable type ofautomatic loom, and parts of a loom particularly adapted for weavingsaid fabric, are shown Vand described in an application for Letters vyPatent, Serial No. 790,327, filed September Having thus described myinvention, what i claim as new and desire to secure by Letters latentis:-,.

1. A woven pile' fabric'4 having a backing web composed of binder warpscrossed at regular intervals, weft threads between said binder warps,lweft/threads on the outer side of said binder warps, and insubstantiall thesame vertical plane as the inner we t threads, pilewarps inclosing'said outer weft I- threads, to forma close loopthereon.'

'2.` A double woven pile fabric, having suitably spaced backing webs,each composed of 'v binder warps crossed atregular intervals,

yweft threads between said binder warps, .weft threads on the outer sideof said binder Warps, and in substantially the same vertical vplane asthe inner weft threads, and two sets yof pile warps, crossing each otherbetween the two backing webs beforebein severed, and passingaround theouter we t I' threads, to form close loops thereon.l

3. A double woven pile fabric, having suitably spaced backing webs,'eachcomposed of binder war s1 crossed at regular intervals,

weft threa s between said binder warps,

weft threads on the outer side of said binder warps, and insubstantially the same vertical plane as the inner weftthreads, and twosets of pile warps, crossingeeach' other between the two backing websforebein severed, and passing around the outer we threads to -Jform twosets of close loops thereon, and when severed, intermediate the backingwebs, vforming a eut pile surface.

4. A wovenpile fabric having a backing web, composed of binder Warpscrossed at regular intervals, weft threads between said binder warps,weft threads lon the outer side of said binder warps, and insubstantially the same vertical plane as the inner weft threads, pilewarps inclosing said outer weft threads to form .'a close loop thereon,and also inclosing the inner "weft threads, lying in substantially thesame vertical palane as v said outer weft threads.
